What is a C71500 copper nickel tube?
ASTM B111 C71500 copper-nickel tube, also known as 70/30 tube, is a non-ferrous metal tubing with excellent thermal conductivity. Manufactured seamlessly using stamping and drawing processes, it is lightweight and has high low-temperature strength. It is commonly used in the manufacture of heat exchange equipment (such as condensers) and in cryogenic piping in oxygen production equipment. Small-diameter copper tubes are often used to transport pressurized liquids (such as lubrication systems and hydraulic systems) and as pressure measuring tubes for instrumentation. C71500 copper-nickel tube, with its high strength and corrosion resistance, has become the preferred material for marine condensers and heat exchangers.

C71500 Copper Nickel Seamless Pipes and Tubes Applications
Q: Is C71500 resistant to biofouling?
A: While not completely anti-fouling, the corrosion product film on C71500 is less conducive to marine organism attachment than many other metals, and the release of copper ions into the water provides a mild biofouling resistance.
Q: How does C71500 resist erosion-corrosion?
A: Its high inherent strength and the durability of its protective film allow it to withstand high flow velocities (typically up to 3.5-4 m/s in seawater) without significant damage.
Q: Can C71500 handle acidic or alkaline environments?
A: It has good resistance to neutral and alkaline solutions and non-oxidizing acids. However, it is not recommended for strongly oxidizing acids like nitric acid.
Q: How do you weld C71500 copper-nickel pipe?
A: It is readily weldable using Gas Tungsten Arc Welding (GTAW/TIG) and Gas Metal Arc Welding (GMAW/MIG) processes. Use matching filler metals like ERCuNi or 70/30 CuNi rods and ensure proper shielding gas to prevent oxidation.
Q: Can C71500 be bent and formed easily?
A: Yes, it has good ductility and can be cold-formed using standard techniques. Annealed temper pipe is preferred for severe forming operations.
